Requesting to be excused from a week

On the Requests tab, "I need out of a week" is how you flag that you can't make a match you're scheduled for.

You can only request out of weeks you're actually scheduled to play, and only once the season is published — the tab explicitly tells you if change requests haven't opened yet. Past and cancelled dates aren't offered — there's nothing left to trade on them. Pick the date, optionally add a short note (e.g. "on holiday") so teammates know why, and hit "Post request."

That posts it with status open. Nothing changes on the schedule yet — posting a request doesn't remove you from the week by itself. It just makes the week visible to teammates as something they can offer to take. What happens next is covered in Replace vs. swap offers and Accepting an offer.

You can cancel a request you posted yourself at any time before it's matched — see Cancelling a request.
